VFS9VD31B223Q91J

Overview

The VFS9VD31B223Q91J is a Murata Electronics EMIGUARD series low-pass LC filter designed for through-hole mounting. It features a capacitance of 0.022 µF and operates within a temperature range of -40°C to +100°C. The component utilizes radial termination with a lead spacing of 2.5 mm, measuring 12 mm in length and 7.5 mm in width. This device serves as an EMI/RFI suppression solution for electronic circuits.

Feature Summary

Provides effective electromagnetic interference (EMI) and radio frequency interference (RFI) suppression through integrated LC filtering topology.
Designed for robust through-hole PCB mounting using radial leads to ensure secure mechanical attachment.

Applications

General EMI/RFI noise suppression in electronic assemblies
Power line filtering applications requiring low-pass characteristics
Circuit protection against high-frequency interference

Procurement Notes

This component is officially classified as obsolete by the manufacturer and is no longer in production. Verification of current availability should focus on surplus distributors or secondary market sources rather than direct manufacturing channels. Designers must confirm end-of-life status before procurement planning.

Selection Notes

Engineers should evaluate alternative components due to the obsolete status of this part. Suitable replacements must match the 0.022 µF capacitance, radial package dimensions, and operating temperature requirements. Cross-referencing with active Murata EMIFIL or EMIGUARD series products is recommended to ensure long-term supply stability.

Part Context

The VFS9VD31B223Q91J belongs to the Murata EMIGUARD product family, which specializes in passive components for noise suppression. This specific model represents a legacy through-hole LC filter variant. Its classification as obsolete indicates it has been superseded by newer generations within the broader EMIFIL and EMIGUARD portfolios.

Replacement Considerations

Publicly confirmed substitute part numbers include DSS1NB32A223Q91A. Engineers should verify electrical compatibility and physical footprint alignment when transitioning to replacement components from the same manufacturer.
